[PLEASE READ!] RIPPING HELP

Hello.
I wanna start off by saying I have attempted ripping from this game MANY times before but the files turned up empty.
That's why I'm posting in the help thread.

A while ago I tried ripping from the dreamcast (and gba) game "Jet grind radio" only to come out with .Bin files that would not open with an extractor or noesis.

I wanted the dreamcast or HD remake models, not the GBA ones.

An HD remake was made called "Jet set radio" and it was for xbox360,ps3,android,PC and ios.

I attempted ripping the models off my android phone, but could not open the game file.

I was wondering if someone could help me figure out how to get these models.
Is there a dreamcast emulator that I can use to snag the 3d models?
Or is there a way to figure out how to open the .bins (note: I don't have the bin files now because that was ages ago, but I could probably get them again later on).

I noticed someone uploaded The sequel to this games models, but I want the model from "Jet set/grind radio"
Not "Jet set radio future"
